This iPhone Setting Can Permanently Turn Off Your Phone

While it's always a fun prank to change the language settings in your friend's iPhone to Korean of Finnish, there's one setting change you should avoid if you don't want to make an enemy of your friend.

A strange bug allows you to brick an iPhone by setting the date to May 1st, 1970 or earlier and it actually works on all iOS devices with a 64-bit processor and iOS 8 or higher, as reported by 9to5 Mac. There's even a Reddit discussion thread devoted to the issue, where one user came up with a good theory as to why this bug exists, and why it might not affect everyone.
